  1. 1. Generell metod för analys av pesticider med HS-SPME i kombination med GC-MS : Möjligheten att identifiera pesticider i känd lösning och i förgiftningsfall

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Samuel Eliasson Heino; [2022]
    Nyckelord :Gas chromatography-mass spectrometry; Pesticides; Intoxication; Limit of detection; headspace-SPME; EPA 8151; Detection; Derivatization; Separation;

    Sammanfattning : This study focuses on a general method that has been developed for the identification of both polar- and nonpolar pesticidespolar pesticides in a known solution from EPA 8151 Herbicide acid mix by Merck including the ordered non-polar pesticide Prosulfocarb. The EPA-solution contains 16 analytes that has been completely identified when derivatized and spiked in acetone. LÄS MER

  3. 2. Stämmer ischemidrabbat koronarartärsområde visat med myokardscintigrafi överens med koronarartärsmorfologi visat med koronarangiografi

    Kandidat-uppsats, Högskolan i Jönköping/HHJ, Avd. för naturvetenskap och biomedicin

    Författare :Carl Bartoli; Magnus Nordlöf; [2018]
    Nyckelord :Koronar revaskularisering; polar plot; perfusion.;

    Sammanfattning : Myocardial Perfusion Imaging (MPI) and Coronary Angiography (CA) are two methods that can be used in the investigation of ischemic heart disease. The purpose of this study is to compare medical answers from MPI and CA to find out if suspected coronary artery disease shown with MPI correlates with coronary artery morphology shown with CA, and which treatment is given based on Summed Difference Percent (SD%).

  4. 3. Optical Spectroscopy of GaN/Al(Ga)N Quantum Dots Grown by Molecular Beam Epitaxy

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Kuan-Hung Yu; [2009]
    Nyckelord :Quantum dots; GaN; AlN; Exciton; Biexciton; micro-Photoluminescence.;

    Sammanfattning : GaN quantum dots grown by molecular beam epitaxy are examined by micro-photoluminescence. The exciton and biexciton emission are identified successfully by power-dependence measurement. With two different samples, it can be deduced that the linewidth of the peaks is narrower in the thicker deposited layer of GaN. LÄS MER
